Add a configuration option, http.sslCertNoPass, and associated
environment variable, GIT_SSL_CERT_NO_PASS, to allow disabling of the
SSL client certificate password prompt from within git. If this option
is set to true, or if the environment variable exists, git falls back to
OpenSSL's prompts (as in earlier versions of git).
This option is useful in (at least) two cases:
1. The certificate is not encrypted and the user does not want to be
prompted needlessly.
2. The user does not wish to leave the password in the clear in git's
(and libcurl's) memory, in case the program crashes and core dumps.
The environment variable may only be used to disable, not to re-enable,
git's password prompt. This behavior mimics GIT_NO_VERIFY; the mere
existence of the variable is all that is checked.
